Aguilera's breathlessly energetic, senses-frazzling live spectacular of a concert brought the house down in Sydney, Australia. And the cameras were there to capture it all for this new concert DVD. The critically acclaimed live extravaganza thrills and awes, while Christina's vocal acrobatics remind you whey hers is the voice of a generation. With 90 minutes of footage - from burlesque cabaret, to trapeze choreography, fire jugglers, and stilt walkers - the lady knows how to put on what's been called "the greatest show on earth!" 18 songs spanning her career are included.
